True
Speed is the _________ at which an object changes _________
Speed is the RATE at which an object changes POSITION
True or False: You find the average speed by multiplying the distance traveled by the total time moving?
False. You divide the distance by the time spent moving
How do you find an object's average speed?
Divide the distance the object moves by the total time spent moving
True or False: The speed of most objects is constant
False. The speed is not constant usually. In other words, objects usually do not move at the same speed all the time.
Think of an example how objects move at different speeds at different times
Riding a bike - sometimes fast, sometimes slow
Driving a car - sometimes zoom, sometimes slow
Disney World Ride - sometimes fast, sometimes slow
We drive to the beach. It is 50 miles away. It takes us 5 hours to get there. What is our average speed? Include your units!
50 miles divided by 5 hours = 10 miles per hour
What combines both speed and direction an object is moving?
Velocity
What is any change in speed or direction of an object's motion?
Acceleration
What are three types of acceleration
Starting, speeding up, slowing down
Velocity = ________ + _________
speed plus direction
15 mph south is an example of ___________
